Question

calculate the mass number of carbon dioxide​

Answer 1

We can calculate the mass of one molecule of carbon dioxide by adding together the masses of 1 atom of carbon and 2 atoms of oxygen. The molecular mass of a compound is the mass of one molecule of that compound. The molecular mass of carbon dioxide is 44.01amu.

Answer 2

Answer:

The molecular mass of carbon dioxide is 44.01amu. The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g. The molar masses are 44.01g/mol and 78.04g/mol respectively.Aug 12, 2020
